Title: Improvements in the compressing of cigarettes for packing
IPC: B65B19/02
Filed: 1960-04-26
Abstract: 941,413. Packaging cigarettes. MOLINS MACHINE CO. Ltd., J. W. CHALMERS, C. T. HALL, and W. A. ROFFEY. April 25, 1961 [April 26, 1960], No. 14591/60. Heading B8C. An apparatus for compressing a batch of loose cigarettes prior to wrapping works in a cycle comprising:- (a) compressing the batch laterally, while allowing vertical expansion; (b) compressing the batch vertically while resisting lateral expansion; (c) holding the batch compressed for part of the cycle; (d) releasing both compressions and allowing the batch to expand; (e) maintaining the batch in the released condition for the remainder of the cycle. Batches of cigarettes are fed into and through the apparatus by a chain conveyer 45 carrying pushers 46, being checked for completeness by a device 47 and aligned by a hinged plate 48. The conveyer, moving intermittently, first advances the batch to a position 3 (Fig. 1) where it is compressed laterally by side-plates 5. On completion of the lateral compression the top plate 7 is lowered to compress the batch vertically. Both compression systems are held for a short period and then partially released, held for a further period in the partially released condition and finally completely released. The conveyer then advances the batch to a position 4 where it is subjected to a similar cycle in which the compressions are more severe. In the next advance the batch engages a web 50 of wrapping material which is then folded and sealed in any desired manner. Operation of the lateral compression plates 5 is by means of cam and follower assemblies 16, 17 and 19, 20 working through suitable linkages (Fig. 2) to reciprocate the plates 5. Operation of the vertical compression plate 7 is by means of a further cam assembly 41, 42 working through linkage (Fig. 3) to reciprocate a sliderod 28 carrying rollers 27 which run on ramps 30 (Fig. 4, not shown) on the plate 7. This plate 7 may be stepped so that extra compression is applied at the second stage. In a modification the second stage of vertical compression is omitted, the final package being of greater height than the original uncompressed batch, only lateral compression having taken place. A modification of the top plate operating assembly is also described (Fig. 7, not shown). The apparatus is adjustable for the amount of both vertical and lateral compression and therefore for the size of the final package.

Title: Improvements in ceiling and wall linings
IPC: E04B9/24
Filed: 1952-06-10
Abstract: 729,460. Wall and ceiling coverings. TEN TEST FIBRE BOARD CO., Ltd., and MITCHELL, D. S. B. June 10, 1953 [June 10, 1952], No. 14606/52. Class 20(4). A ceiling, or wall, lining is constructed from panels 1 which are supported from the flanges 6 of inverted T-section rails 7 arranged across the ceiling, or wall, as supporting members. As a panel 1 is brought into position between two adjacent rails 7, clips 5, mounted on battens 2 set back slightly from the marginal portions of two opposite sides on the unexposed face of each panel, are turned to engage the adjacent flanges 6 of the pair of rails 7. A batten 3 is arranged to overhang a third side of each panel, the fourth side of which is left free so that as a panel is offered up between a pair of rails 7 the batten 3 on that panel will overlap the free edge 4 of the panel previously secured in place. In order to retain the panels in even plane spikes 8 are driven into the end edges of the panels for engagement with the corresponding edges of adjacent panels. In a modification U-shaped clips are employed, one limb of the clip terminating in a spike adapted to engage in, or under, a batten 2 and the other limb being adapted to engage a flange 6. In a further modification each spring clip is mounted on a pivot pin which is engaged in a slot in the edge of a batten 2, the head of the pivot pin being located between the batten 2 and the panel 1 and a clip being mounted on the pivot pin to hold the spring clip in place. In an alternative arrangement the spring clips associated with the pivot pins may be dispensed with, the pivot pins in this case having securing devices incorporated at their free ends. The panels 1 are preferably made of fibre board with timber or fibre board battens, but other materials, e.g. asbestos sheets, plaster or hard board, &c. may be used.

Title: White balance control system
IPC: H04N9/077
Filed: 1972-03-29
Abstract: 1373279 Colour television SONY CORP 29 March 1972 [30 March 1971] 14831/72 Heading H4F  Loss of white balance in the NTSC chrominance signal from a colour television camera due to a change in the colour temperature of the illumination of a viewed scene (e.g. between studio lighting and sunlight) is corrected by adding to the chrominance signal at 61 a signal at the chrominance subcarrier frequency from reference oscillator 44 which has been phase shifted at 59 and amplitude modulated at 60 by part of the luminance signal to be of the correct phase and amplitude to restore white balance. Three positions of switch 64 are provided to allow for corrections for two illuminations other than that for which the camera optics is set. The attenuation factor of attenuator 65 feeding the luminance signal to the modulator 60 may be varied in response to switch 64, or in response to a variable phase shifter substituted for the phase shifters 62 and 63 shown. Attenuator 65 may alternatively be used between modulator 60 and adder 61, the luminance signal being fed directly to modulator 60. The white balance correction is described as applied to a single-tube camera of the type described in Specification 1,371,355 having a red, green, cyan striped filter and two striped electrodes fed by opposite phase signals via a transformer from a half line frequency square wave generator. The resulting chrominance and index signals are separated at 20 and 21 by the use of a one-line (or three- or five-line) delay line 19. The luminance signal from low-pass filter 17 is converted to NTSC form by adding a correction signal to it at 56, the correct relative amplitudes of the red, green and blue signals in the correction signal being produced by phase detecting at 57 the chrominance signal from 20 along an axis lagging by 49 degrees the phase of the green signal in the chrominance signal at 20 (Fig. 16, not shown). The chrominance signal is altered so as to be on a subcarrier of stable NTSC frequency by the use of oscillator 44, amplitude modulators 43, 42 and band-pass filters 45, 46, the resulting signal being phase altered in amplitude modulator 47 to produce red, green and blue signals at correct relative phases and amplitudes for NTSC. This chrominance signal is then advanced 3 degrees in phase and its amplitude is multiplied by <SP>1</SP>/ 1À61  to give an NTSC chrominance signal to which is added bursts at 51, the white balance corrrection signal at 61 and the NTSC luminance signal at 53.

Title: Improvements in Sewing Machines.
Inventor: WILLIAMS FREDERIC SOLOMON
IPC: D05B23/00
Filed: 1918-09-13
Abstract: 127,480. Williams, F. S. Sept. 13, 1918. Sewing-machines; work supports; lock-stitching by shuttles.-Relates to lock-stitch sewing-machines in which the work is supported on a hollow work-support 25, and the needle-thread loop has to be drawn downwards into position to be entered by the shuttle by a supplementary hook 72, and consists in the means provided for preventing the strands of the needle-thread loop from becoming twisted during the take-up. The needle is set so that the eye is disposed in the line of feed, and a blade 31 is disposed lengthways in the work-support so as to lie between the strands of the needle-thread loop when the shuttle has been passed through it. The blade 31 is bent so that its upper end 33 lies in a plane parallel to the line of feed, and its lower end is at rightangles thereto, and is loosely mounted on the stud 36, which is provided on the shuttle 37 for supporting the bobbin. A tail-piece 39 on the blade engages a notch 40 on the bobbin to hold it against rotation. The shuttle 37 is of the oscillating type, and is connected to the pin 36 by a single arm 38 to allow sufficient clearance for its movements. It runs in a raceway 48 with a section pivoted at 52 and regained by a bolt 53. It is actuated by a driver 54 carried by a shaft 59 which is rocked by a pinion 63 gearing with a rack on the end of lever 65 actuated by a cam 70 on a vertical shaft 71. The plane of oscillation of the shuttle is at right-angles to the direction of feed and to the plane containing the needlethread loop. The supplementary hook 72 slides in a guide 74 and is reciprocated lengthways of the work-support by a lever 83 actuated by a cam 87 on the shaft 71. The guide 74 is mounted on a universal pivot at its lower end, and is rocked parallel to the plane of movement of the shuttle to give the hook the necessary movements for avoiding the needle and entering the needlethread loop by a pivotally and slidably mounted fork 92 engaging a grooved collar 90 on the guide. The fork 92 is connected by a cam 96 with a lever 97 actuated by a cam 102. The fork 92 is also anchored to the machine frame by a link which causes the guide 74, with the hook 72 at its lowest position, to have a movement away from the shuttle.

Title: Improvements in and relating to electric relays
IPC: H01H83/14
Filed: 1922-05-27
Abstract: 202,744. British Thomson-Houston Co., Ltd., (General Electric Co.). May 27, 1922. Electromagnetic switches; induction relays; automatic c i r c u i t - breakers; protective arrangements.- Alternating-current induction relays have a torque produced in a disc by the rotating field of a polyphase electromagnetic structure and a magnetic member mounted concentrically with the cores of the electromagnets to produce a second opposing torque so that upon any phase opening or reversal a reverse rotation of the disc takes place and trips a switch controlling the polyphase supply. In Fig. 1, two pairs of electromagnets 10, 12 and 11, 13 are connected in two phases of a 3-phase supply inducing a clockwise torque in the disc 10. A magnetic member 21 is secured to the disc and has pole pieces co-operating with the cores 14 of the electromagnets 10 - - 13 in such a manner that when the projection 23 is held against a stop 22 there is an opposing torque due to the attraction of the member 21. If the rotating field collapses due to a fault in any phase, the attraction of the member 21 produces an anti-clockwise rotation of the disc enabling the projection 23 to engage a switch tripping lever 25. In the modification shown in Figs. 2 and 3 the magnetic member 21 is normally stationary but may be adjusted, being mounted relatively to the cores 14, 17 of the pole electromagnets 11 - - 13 so that the clockwise torque in the disc 19 due to the rotating field is opposed by, but normally predominates over torques at the pole-pieces. Any phase interruption however destroys the clockwise torque allowing the disc, which is normally held against a stop 24, to be rotated in an anti-clockwise direction allowing the peripheral projection 23 to engage the switch trip lever 25. Fig. 4 shows this switch in which on depressing the knob 31 the contact 29 is brought into engagement with the fixed contact 30 the switch being latched in its closed position by the pivoted latch 25 against the action of the return spring 32. Fig. 5 shows the application of the relay to a 3-phase circuit in which the coils 10, 12 and 11, 13 are in series with two phases of the supply to a 3-phase motor M. On interruption or reversal of any phase the switch 26 is tripped open thus breaking the circuit of the coil 33 and allowing the circuit breaker 27 to open the supply circuit from A.

Holders or tobacco pipes 2 receive containers 12 shaped like cigars, cigarettes or tobacco cartridges which are pricked by spring-loaded pins 11 acting also as valves which, when mouthpieces 1 are partially unscrewed, are opened by suction to allow passage from the containers of compressed tobacco smoke or other smokes or gases having an effect similar to the flavour of tobacco smoke. In the case of a pipe a slider 13 is provided to withdraw the pin 11 if it sticks in the container 12, but this is dispensed with in the case of a holder as the container is made to screw thereinto and may be partially undone for the same purpose. The pipe bowls are asymmetrical to prevent rotation of the containers 12 therein. The holders, pipes and containers may be provided with filters. Tobacco smoke in the containers may have been filtered, dehydrated or flavoured before introduction thereinto. The holders may be of artificial resin, and co-act with containers of a transparent artificial resin e.g. " Plexiglass " (Registered Trade Mark).

Title: A process for the cyanoethylation of fabrics of cellulose fibres
IPC: C08B11/155
Filed: 1961-04-27
Abstract: Fabrics of natural or regenerated cellulose are uniformly cyanoethylated to an optimum nitrogen content of 2,5-4,0% by impregnating with dilute aqueous alkali hydroxide solution, squeezing out to a liquid content of at least 60%, preferably 60-150%, pading on a foulard with a minimum amount of acrylonitrile, squeezing out to a liquid content at least 25% higher than in the pre-treatment, e.g. 80-175%, and after-treating in an air-tight, thermally insulated closed space saturated with acrylonitrile vapour.  The after-treatment may comprise placing the fabric in an insulated polythene bag, suitably for 1 to 20 hours depending on the temperature (10 DEG -50 DEG C.).  The uniformity of the cyanoethylation is assessed by dyeing tests on the acid-washed, rinsed and dried fabric.  In an example, cotton fabric is impregnated on a foulard with 8% aqueous sodium hydroxide, squeezed out to 91% liquid content, padded on a second foulard with acrylonitrile and squeezed out to 120% liquid content.  The fabric is then left in a polythene bag for 3 1/2 hours at room temperature, acidified, rinsed and dried to yield a cyanoethylated fabric of nitrogen content 3,8%.

Title: Improvements in the Manufacture of Chlorhydrins and Bromhydrins of Olefinic Hydro-carbons.
IPC: C07C29/66
Filed: 1919-06-19
Abstract: 128,578. Commercial Research Co., (Assignees of Brooks, B. T.). June 20, 1918, [Convention date]. Hypochlorous acid; hypobromous acid.-Chlorhydrins and bromhydrins are prepared by subjecting gaseous olefinic hydrocarbons, under pressure, to the action of a weak aqueous solution of hypochlorous or hypobromous acid. The reaction is effected in a vessel A filled with an inert packing. In making chlorhydrins, hydrocarbon gases are pumped through an inlet D and excess escapes through a valve f and meter G. Hypochlorous acid solution is sprayed into the vessel A from a pipe H by a pump I. The chlorhydrin solution is discharged by a pipe B to a storage vessel C from which it may be passed through an apparatus in which hypochlorous acid is formed and thence is returned to the vessel A to obtain a stronger solution of chlorhydrins. The hypochlorous acid is formed by passing water or chlorhydrin solution from the vessel C into a mixing- vessel 0 containing a salt of a weak acid such as sodium bicarbonate, borax, &c. or a mixture of sodium bicarbonate and boric acid, or a basic salt such as magnesium oxychloride. The solution obtained is passed by a pipe P down a stone-ware column Q up which chlorine, is passed from a container U through a meter T. Excess of chlorine escapes by a pipe q<1>. Specification 128,635 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes also the use of salts of hypochlorous acid such as magnesium, calcium or aluminium hypochloride in place of the basic salts present during the formation of hypochlorous acid. This subject-matter does not appear in the Specification as accepted.
